My van lost all power while driving yesterday.

What is your question?

I drove approximately 200 miles yesterday. Towards the end of the trip, while on a highway, my car lost all power. The cruise control worked intermittently during the trip. Prior to this, a computer board is going / has gone bad. One of the phone chargers doesn't work, the odometer doesn't show, and the rear windows are inoperable. Not sure if these are connected. Any ideas?
